103 Multi-Speed Brake Lathe
DEPTH OF CUT DIAL
1. The drum depth-of-cut micrometer is located on the
cross slide handwheel (Figure 16). This handwheel is
used for moving the tool bit into the brake drum. The
dial has a scale to indicate amount of material to be
removed from the drum diameter.
2. The divisions on the handwheel dial are 0.002" and the
scale is direct reading. For example, if the scale is
i n c reased .016" (8 divisions) there will be .008"
removed from each side of the drum increasing the
diameter by .016". No calculations have to be made by
the operator.
DRUM BAR TOOLING ASSEMBLY
The 103 Drum Bar, Part Number 804-8671-10, is machined at both ends. The end of the bar
with the machined slot and the two set screws is used for larger drums and flywheels. The
end of the bar that is reduced in width is for machining small drums. Two drums bits are
included with the 103, therefore is is recommended that a bit is installed in each end.
1. Insert the drum bit in the Tool Bit Holder, Part #804-3021-71 (Figure 17).
2. Assemble the bit clamp and set screw (Figure 18).
Tighten securely.
3. Place the Tool Bit Holder Assembly in the end slot of the drum bar and tighten the two
set screws (Figure 19).
4. Insert the other drum bit in the slot provided in the narrow end of the drum bar. Make
certain the bit is inserted as far as possible (Figure 20).
5. Tighten set screw
(Figure 21).

P R E PARING DRUMS FOR MACHINING
1. First, measure the diameter of the drum with a micrometer to determine that the drum will be within
maximum oversize limits after reconditioning. The drum should also be in good general condition. THE
MAXIMUM REBORING LIMIT DIMENSION IS CAST INTO THE DRUM BY THE MANUFACTURER. NEVER
EXCEED THIS LIMIT OR THE DRUM COULD FAIL IN USE RESULTING IN BRAKE FAILURE.
IMPORTANT: To prevent galling, scratching the newly machined surface clean the drum before mounting.
Use a wire brush or a rotary wire brush in a drill to thoroughly clean all mounting surfaces. Make certain
all rust is removed from both inside and outside bolt patterns and that the inside diameter of the center bore
is absolutely clean and free from any burrs.
